    Hey guys.

    Im in quite the predicament after installing lion on my 2010 Mac book pro.

    I use the machine for audio and many program's, plugins & drivers are not working, hence i want to use time machine to revert to snow leopard.

    Here lies my problem.
    I have taken out computers optical drive and replaced with an ssd drive for second hard drive.

    Im aware that i need to boot from the snow leopard install and have tried from an external cd drive, usb & SD card with no luck, after the boot selection screen (after holding down option) and then choosing the option , the screen does not progress from the grey apple screen.

    Please help or put forward other ideas. i need to get the snow leopard to boot.

    & for all those pro users out there, dont risk lion, it's just not worth it!!!!

    thank you

    Try holding command + v when booting from your USB stick. At what line does it hang?
